The Chicago Marathon is Sunday, and with it will come heightened security around the city. Marathon organizers have taken a hint from the NFL and instituted a clear bag policy for all runners, while also planning to do routine searches of bags for all marathon attendees. Storing your items in a clear bag is an easy way to ensure security and avoid further searches through your items.

The four bags we'veve selected pass standards outlined by the NFL's website and are practical options for marathon spectators.
